Description

Technical Field

[0001] This utility model relates to the field of automotive radar technology, and in particular to a split-type autonomous driving radar housing. Background Technology

[0002] As autonomous driving technology advances to Level 3 and above, sensors such as LiDAR and millimeter-wave radar, as core components for vehicle environmental perception, directly affect the safety and stability of autonomous driving systems in terms of performance and reliability. However, existing integrated radar housings have revealed many technical bottlenecks in practical applications.

[0003] To achieve higher precision environmental perception, radar needs to integrate more high-power chips and laser emission modules, which leads to a sharp increase in internal heat density. Traditional integrated housings mostly use passive heat dissipation or single active heat dissipation, which is difficult to meet the heat dissipation requirements of high-power radar in a small space. Especially in high-temperature environments or long-term continuous operation scenarios, it is easy to cause chip overheating and frequency reduction, reducing radar detection accuracy. Therefore, we need to upgrade and modify the existing technology to overcome the existing problems and shortcomings. Utility Model Content

[0004] The purpose of this invention is to provide a split-type autonomous driving radar housing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The lower outer side of the housing body is provided with a mounting plate and multiple sets of external mounting holes are provided on the mounting plate. The lidar is installed inside the housing body. The lidar has a transmitter at its front end and the transmitter extends through to the front end of the housing body. The heat dissipation component is installed on both sides of the housing body. The limiting component is located inside the housing body.

[0007] The heat dissipation assembly includes a side block fixed to the side wall of the outer casing, with a vent penetrating through the side block. An exhaust fan is installed inside the vent, and a louver is provided outside the vent. A dustproof net is provided between the louver and the exhaust fan.

[0009] Preferably, the rain guide strip has multiple sets of fixing holes on its side, and fixing bolts are connected between the fixing holes and the side block.

[0010] Preferably, the limiting component includes a fixing plate installed on the inner wall of the outer shell, the fixing plate having a limiting hole at its front end and a front opening at the front end of the limiting hole, and a protective pad being provided inside the limiting hole.

[0012] Preferably, the outer wall of the lidar is provided with a plurality of heat dissipation fins, and the side of the lidar is provided with an inner mounting hole, and an inner bolt is screwed between the inner mounting hole and the outer shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

Louvers and dustproof nets provide rain and dust protection. Rainwater is guided from the side blocks to the rear via rain guides and a drainage channel. This effectively and actively dissipates heat from the lidar, ensuring stable operation and preventing overheating due to direct sunlight. It also provides excellent protection against dust and rainwater entering the device through the heat dissipation structure, thus improving the device's reliability and lifespan.

[0015] 2. This utility model has a limiting component inside the device. The fixing plate is installed in the outer shell through the connecting hole and the connecting bolt. The equipment wire harness is snapped into the limiting hole through the front opening. This can effectively limit and protect the radar wire harness, which can ensure the connection stability and safety of the radar wire harness and prevent it from loosening and tangling during use. This further improves the safety and practicality of the equipment.

The fixing plate 51 is installed inside the outer casing 1 through the connecting holes 54 and the connecting bolts 55. The equipment wire harness is snapped into the limiting hole 52 through the front opening 53. This can effectively limit and protect the radar wire harness, which can ensure the connection stability and safety of the radar wire harness and prevent it from loosening and tangling during use, thus further improving the safety and practicality of the equipment.

[0027] The working principle and operation process of this utility model are as follows: When in use, the lidar 3 is installed inside the outer shell 1 and fixed by the inner bolt 34. The equipment wiring harness is snapped into the limiting hole 52 through the front opening 53 to achieve effective limiting protection of the lidar wiring harness. The entire device is installed on the roof of the vehicle by the cooperation of the mounting plate 2 and the outer mounting hole 21. When in use, the ventilation fan 43 is turned on to exchange air between the inside of the outer shell 1 and the outside. The louvers 44 and the dustproof net 45 are used to block rain and dust. The rain guide strip 46 and the drain trough 49 are used to guide the rainwater on the side block 41 from the rear, which can achieve effective active heat dissipation of the lidar 3 and maintain the stable operation of the lidar 3.
